Power plant steam turbine generator bedplate of how to use high strength grouting material construction

High strength grouting material with high strength grouting material steam turbine generator is all power plants 'heart'. Assumes that the steam turbine generator bedplate and touch the bad block, unit will start oscillation and affect the normal power plant safety and safe operation. Therefore, it is necessary to ensure the bedplate and block touch with smooth surface, to ensure that the touch area rate with high accuracy requirements, then make sure that all the steam turbine generator bearing reasonable. Bedplate of steam turbine generator block selects the high strength without the place of traditional shim can shorten the grouting material is very good good technical requirements, the bearing capacity, construction period, reduce the human has a clear role, and use is becoming more and more popular. Scope of power station steam turbine generator bedplate grouting construction technology principle of block grouting material has the characteristics of their functions better, in the construction using the template height difference on both sides of the turbine bedplate, let the grouting material free activities, in this state and turbine bedplate bottom touch tightly, arrived in touch with smooth surface between block and counter, and then make sure touch area rate. Block casting casting, casting two stop. In the first layer after pouring start pouring the second 20 to 40 minutes. The pause time is too long will incur a isolation layer. Best environmental temperature should be 15 ~ 25 ℃, casting about 40 mm high, for the first time writing bedplate of nozzle should be lower than the bottom 30 ~ 40 mm. In the first layer of casting after the completion of 20 ~ 40 minutes start pouring the second layer, casting the second layer, should be until the mortar overflow talents suspension casting sprue gate. After pouring after 20 ~ 40 minutes, using the bedplate of deck along the edge to edge 'fat'.
